[0020] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: a formwork system that is easy to disassemble and assemble, including connecting steel bars 7 and a base layer 10, a cushion layer 9 is fixed above the base layer 10, and a bottom plate 8 is fixed above the cushion layer 9;

[0022] The connecting steel bar 7 is provided with a removal force point 6, and the inner vertical steel bars 1 are matched with the gaps at both ends of the outer side below the connecting steel bar 7 to ensure that the clearance of the side ditch (or intercepting ditch, etc.) meets the design requirements, and the lower end of the inner vertical steel bar 1 is tilted inwards for easy installation;

[0023] The gaps at both ends of the inner side below the connecting steel bar 7 are matched with the outer vertical steel bars 2, and the lower ends of the outer vertical steel bars 2 are tilted outwards for easy installation; the outer vertical steel bars 2 are bent inwards at the middle and lower parts, so that the template can be well fixed and easy to disassemble;

[0024] A template limiting device 3 is installed at the lower end of the connecting steel bar 7. The tail of the template limiting device 3 is tilted inward to prevent the template from sinking inward to ensure that the wall size is qualified;

[0025] The two inner vertical steel bars 1 are fixed with inner frame support rods 4 on the side. The two inner frame support rods 4 are on the same axis. The ends of the inner frame support rods 4 are turned with reverse threads. They are located on the back edge of the template for easy force bearing. The length is short and the net width is designed.

[0026] The two ends of the inner support rod 4 of the skeleton are threadedly connected with reverse-thread straight thread sleeves 5, and the reverse-thread straight thread sleeves 5 are rotated to adjust the tightness of the inner support.

[0027] Working principle: the gap between the connecting steel bars 7 is matched with the inner vertical steel bars 1 and the outer vertical steel bars 2. The lower end of the inner vertical steel bar 1 is tilted inward to ensure that the clearance of the side ditch meets the design requirements. The outer vertical steel bar 2 fixes the outer formwork of the wall. The outer vertical steel bar 2 is bent inward at the middle and lower part of the steel bar to fix the formwork well. The formwork limit device 3 is fixed by screws below the connecting steel bar 7 to prevent the formwork from sinking inward to ensure that the wall size is qualified. The support rods 4 in the skeleton are designed with threads. The two support rods 4 in the skeleton are located on the same axis and lower on the back rib of the template for easy force bearing; the reverse thread straight thread sleeve 5 and the inner support of the skeleton can be adjusted by rotation to facilitate installation and disassembly; when dismantling, you need to loosen the bottom reverse thread straight thread sleeve 5 first, use a hammer to tap upwards on both sides of the clamp to remove the force points 6, and take them out after loosening, which greatly reduces the workload of template reinforcement and demolding, and better controls the size.

[0028] When the project volume is large, it is recommended that the formwork system adopts steel formwork (such as Figure 2-Figure 3 ), stiffening plates should be added to the bottom and top of the back of the formwork to better reinforce the skeleton piece and make it easier to install and disassemble; when the project volume is small, wooden formwork (such as Figure 4-Figure 5 ), back ribs must also be set at the top and bottom of the wooden formwork, and the bending starting point of the vertical steel bar 2 on the outside of the clamp exceeds the upper back rib to ensure that the clamp is subjected to reasonable force.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
